Next Best Upgrade for Tidal MQA?


I’m trying to decide what my next best upgrade is going to be to improve my streaming music quality (predominantly Tidal, and Tidal MQA, when available).

Current setup:
KEF R11
Custom Deep Sea Sound 18” subs (2)
Marantz SR7012 AVR
Bluesound Node 2i
MyTek Liberty DAC
Parasound A21+

I’m wondering if I’ll get a bigger jump from inserting a Parasound JC2 BP as a pre-amp or replacing the DAC/Streamer with a MyTek Brooklyn Bridge? Or is there something else out there in the $2500-4000 range that will help make a significant jump?

Help and thoughts appreciated!

Depending on your budget I would start with the following 

If you have not already done so -  Upgrade your coax connection from the DAC to your Preamp/component system.  You will be amazed at what an improvement in the sound you will get.   Pangea Audio Premier XL Digital Cable with Cardas Copper - is a good option for the money. 

Another option is to upgrade your DAC to one with a newer DAC chipset 
for example - the  auralic altair g1 ( with the ESS 9038Q2M chipset) -  would replace the Node 2i and the mytec DAC. 

Have you thought about your network? UpTone Audio EtherREGEN switch was an upgrade several audiophile have tried and had good results.
I heard a big difference going from Node 2i to Lumin streamer. More separation and definition in the sound. Going thru Aries DAC and 300B tube amp or Yamaha A-S2200.
